Abstract

The invention relates to a self-energized damping-adjustable shock-absorbing device, which belongs to the technical field of energy conservation and emission reduction for automobiles. The self-energized damping-adjustable shock-absorbing device comprises a linear motor, a magneto-rheological damper, a bridge type rectifier, a DC-DC convertor and an accumulator, wherein the linear motor and the magneto-rheological damper are connected integrally and coaxially; one end of the bridge type rectifier 19 is connected with the linear motor, and the other end of the bridge type rectifier 19 is connected with one end of the DC-DC convertor; the other end of the DC-DC convertor is connected with the accumulator 25, so that energy is recovered; and the output end of the accumulator 25 is electrically connected with a magnet exciting coil 8 and transmits the stored electric energy to the magnet exciting coil 8. The stored electric energy is used for adjusting the current of the magnet exciting coil 8, so that the damping of the magneto-rheological damper 15 can be adjusted; and at the same time, the damping force of the linear motor is adjusted by adjusting the voltage output to a suspension according to different modes of the DC-DC convertor, so that a state of self-energization and dual damping effect is realized.

Description

technical field [0001] The invention relates to the field of automobile energy saving and emission reduction, and specifically relates to a self-supplied energy damping adjustable vibration reduction device. Background technique [0002] Shock absorber is a crucial part of the car suspension, and its performance directly affects the ride comfort and handling stability of the car. At present, we usually use the traditional twin-tube hydraulic shock absorber on the passive suspension, and its damping cannot be adjusted, so the corresponding damping characteristics cannot be adjusted according to road conditions, loads, etc., and a good vibration reduction effect cannot be achieved. At the same time, when the car is running on the road, due to the unevenness of the road or more complicated working conditions, part of the energy of the car is consumed in the form of heat during the vibration of the suspension. If this energy is recovered, the fuel consumption will be greatly red...
